An attacker could intercept wireless signals with a powerful antenna and "broadcast a stronger signal," which would cause blood-sugar levels on the monitor to change

Wireless
medical devices such as pacemakers, insulin pumps and
defibrillators have made life not only possible for those who use them, but
convenient as well since there are no cords to mess around with. On the other
hand, there are dangers associated with using such equipment: hackers.

Hackers are commonly associated with computer systems, where websites are
broken into and private information is sometimes stolen. In 2011 alone, cyber
criminals have attacked and stolen information from Sony, the Pentagon, Bank of America and
many more. But in this particular case, hackers could move from traditional
mediums to the hacking of wireless medical devices.

Jerome Radcliffe, a security researcher, is a diabetic who uses an insulin pump
and a glucose monitor at all times to control his blood sugar. He has become
increasingly interested in the security of the medical device that is saving
his life, and set out to see if proprietary wireless communication could be
reverse-engineered while a device launches an attack that could manipulate a
diabetic's insulin, potentially leading to death.

Computer scientists have already proved that pacemakers
and defibrillators can be hacked wirelessly through the use of radio
hardware, an antenna and a PC. This research was published in a 2008 paper,
which described how an attacker could send a lethal shock to an implantable
cardiac defibrillator.

Now, Radcliffe has found that a lethal attack is possible against those with
insulin pumps/glucose monitors as well. According to Radcliffe's research, an
attacker could intercept wireless signals with a powerful antenna and
"broadcast a stronger signal," which would cause blood-sugar levels
on the monitor to change. This causes the person wearing the pump to adjust the
insulin dosage, and constant adjustment (when it is unnecessary) could cause a
severe "high" or severe "low" in the diabetic's blood
sugar, possibly leading to death.

Radcliffe added that an attacker could accomplish this within a couple hundred
feet of a victim, but with a stronger antenna, it can be done up to a half-mile
away.

"My initial reaction was that this is really cool from a technical
perspective," said Radcliffe. "The second reaction was one of maybe
sheer terror, to know that there's no security around the devices which are a
very active part of keeping me alive."

One has to wonder what would cause a person to want to hack a wireless medical
device and put a person's life at risk. Dr. William Maisel, an assistant
professor at Harvard Medical School, offered some perspective on the matter.

"Motivation for such actions might include the acquisition of private
information for financial gain or competitive advantage; damage to a device
manufacturer's reputation; sabotage by a disgruntled employee, dissatisfied
customer or terrorist to inflict financial or personal injury; or simply the
satisfaction of the attacker's ego," said Maisel.

Allthough you might need to check every time or so.There is still a delay when insuline is active and breaking down the sugar. It is dangerous and lethal aswell. Especially when they give an overdose of 3ml (300 units)

I use manual injection though.I once chose the wrong insuline and gave myself an overdosis (stupid doh) felt really really bad, drank 2 mugs of pure syrup (awfull) and dextro and all that.I don't even want to imagine the full 300 units inside your body.

It probably will send you in a coma... Dangerous stuff.
